Answer:
The correct answer would be C, Arteries carry oxygenated blood while veins carry blood low in oxygen.
Step-by-step explanation:
Arteries are the tubes made up of muscles which take the blood to the heart after the process of oxygenation. Oxygenation is the process in which the blood is purified and then transferred to the heart through arteries. Veins are the part of blood circulation system. These are the tubes, which carry blood which are low in oxygen, or we can say that veins carry oxygen depleted blood to different parts of the body. So this is the main difference that arteries contain fully oxygenated blood while veins contain oxygen depleted blood.
